VEHICLE-SEAT LOCK.

SPECIFICATION forming part of Letters Patent No. 433,081, dated July 29, 1890.

Application iilcd January 24, 1890. Serial No. 338,038. (No model.)

.To all whom t may concern:

Be it known that I, ADOLPH JAENICKE, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented a new and useful Vehicle-Seat Lock, ot which the following is a specification.

My invention relates to improvements in scat-locks for seats having end bars, which are adapted to rest on supporting-ribs of the vehicle-body; and the objects of my improvements are, first, to automatically cause the end bars of thc seat to be locked or secured to the vehicle-body ribs by downward pressure upon suoli seat, second, to afford facilities for readily unlocking' the seat, and, third, to provide a lock which will permit the seat to be moved on the ribs to any part of the vehicle-body, and then lock the seat end bars in the desired position. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my lock attached to the end bar of a seat, the end bar, side-board of the vehicle-body, and supporting-rib being shown only in section, and the seat not being shown. Fig. 2 is a vertical central section of my lock as it appeals out of its operative position.

Similar letters and igures refer to similar parts throughout the several views.

A is a section of an end bar of a seat.

B is a section of a side-board of a vehiclebody, and C is a section of a supporting-rib attached to such side-board.

Each end bar A of the seat is recessed in its bottom and inner side, as at 10. A slideway or bolt-case 1l is attached to the inner sides of each end bar of the seat, and the end of a flat spring 12 is attached to the boltcase near its upper end, and the lower end of such spring is also -provided with a catch 13. Such-slideway or bolt-case is also provided with a perforation 14, registering with said catch 13. At the upper end of thc slideway or bolt-case 11 and above the upper end of flat spring 12 is a projecting bracket 15, provided with a vertical aperture 16. A bolt 17 is inserted within the slideway or boltcase, and its lower end is provided with a foot or projection 18, and upon the front face of such bolt is a slot 19, which registers with' the catch 13. At the upper end of such bolt is a slotted projection 20, within which is inserted the upper end of the bar 21, which is hinged upon the pin 22. The lower end of bar 21 is bent, as at 23, to form a hook.

I have not shown -in the drawings a vehicle-seat, as such construction is well known. The ends of seats are supported upon or by two end bars, and such end bars rest upon supporting-ribs, one att-ached on the inner side of each of the two side-boards of the vehicle-body. t

1n the drawings, Fig. 1 shows my device when in an operative position, and Fig. 2 shows it when out of the operative position.

It will be understood that the inner side of cach end bar oi' the seat is provided with my device. So, too, it will be understood that the lower end of each end bar is cut out or recessed, as shown in Fig. 2 at 10.

To use my device I disengagc the springactuated catch 13 from the slot 1Q in the bolt 17, and then pull the bolt downward in its slideway or bolt-case, so that the foot 18 of such bolt is a short distance below the bottom of the end bar. The seat, with its end bars, is then placed crosswise between the side-boards of the vehicle-body, so that each end bar is over one of the supportingribs, the foot 1S of each bolt being supported upon one of each ribs, as shown in Fig. 2. The operator then sits down upon or presses downward upon the seat, causing thc end bars of the seat to move downward, so that the bottom of each rests upon one of such supporting-ribs. The movement of the end bar downward causes the bolt to move upward in its slideway or boltcase, so as to bringits foot within the recessed part 10 of the end bar, and at the same time the ba12l is moved upward, and the aperture 16 in the bracket 15 guides such bar so as to cause its hook to move toward t-he sideboard and beneath the under surface of the supporting-rib. When such position is att-ained, the slot in the bar is in a position of registration with the perforation 14C in the slideway or bolt-case, and the spring then forces the catch 13 in such slot, and thus locks IOO each seat end bar to a supporting-rib on the side-boards of the vehicle-body. Such position is shown in. Fig. l.

In unlocking the end bars of the seat the operator disengages the catch 13 from the slot in the bolt by pulling the vend of the spring, and then forces the end bar upward, which movement also swings or forces the hook of the bar from under the supporting-rib, thus unlocking such end bars.

I do not claim, broadly7 any device for holding the bottoms of the end bars of a seat upon the supporting-ribs upon the side-boards of a vehicle-body, Where clamps-are attached to such end bars, which exert an upward pressure against t-he under side of the supportingribs.

Vhat I do claim as new, and desire to secure by Letters Patent, is-
